Galvanised Firetainer® Tanks

Where space is limited but dependable fire water storage is essential, galvanised Firetainer® tanks provide an efficient and proven solution. Manufactured by Franklin Hodge, these site-assembled sectional tanks are trusted in both commercial and industrial environments for their strength, flexibility, and certified performance. 

Designed to make the best use of restricted areas such as basements, lofts, or narrow plantrooms, Firetainer® tanks ensure compliance and safety without compromising capacity or build quality. 

The Benefits of Galvanised Firetainer® Tanks 

LPCB-Approved for Fire Safety: Every Firetainer® tank is certified by the UK Loss Prevention Certification Board (LPCB) for the storage of fire sprinkler water. This provides full assurance that your system meets the required standards for fire safety compliance. 

Durable and Corrosion-Resistant: Constructed from galvanised steel panels with a hot-dip finish, each tank offers exceptional protection against corrosion. The shell panels are produced to BS EN 10346 Grade S250GD + Z600-M, ensuring a long operational life with minimal maintenance. 

Adaptable Design for Confined Spaces: Firetainer® tanks can be configured in rectangular or square layouts, allowing them to fit around existing structures such as building columns. Their modular construction means each installation can be tailored to make the best use of available space. 

Low-Maintenance Performance: The internal membrane liner separates stored water from the tank shell, preventing corrosion and ensuring that the structure remains protected over time. The liner material is designed to resist wear, rot, and degradation under normal storage conditions. 

Design and Installation Features 

The Firetainer® system combines structural efficiency with straightforward installation. There is no need for sealants or complex foundation sealing. The liner includes an integrated floor, and the tank shell is simply bolted to the supporting surface. This approach makes assembly fast and accurate, ideal for sites where downtime must be kept to a minimum. 

Tanks can be installed on any suitable flat, load-bearing slab such as a reinforced concrete floor or roof deck. Standard height options range from 1.25 m to 5.35 m, allowing for flexible capacity depending on site requirements. 

Accessories and Optional Features 

Firetainer® tanks are supplied with a comprehensive range of accessories to enhance usability and safety. These include ball float valves, level switches, immersion heaters for outdoor use, anti-vortex devices, contents gauges, and internal ladders. 
For accessibility, external ladders and landings can also be fitted, along with WRc Type ‘AB’ airgaps for potable separation where required. 

Covers are available in two configurations: a flat design with a raised ball-valve housing for indoor use, or a low-profile pitched roof for outdoor locations.
